| 摘 要： | 通过流变学方法探讨了钠、钾离子对硅溶胶体系稳定性与流变性的影响,分析了其作用机理。结果表明:钾离子对硅溶胶稳定性与流变性的影响比钠离子大;在低剪切速率下,所研究的体系表现出剪切变稀的流变学特性,而在高剪切速率下则表现出类牛顿流体的特性。

| Abstract: | The influence of K+and Na+concentrations on the stability and rheological property of silica sol system have been studied by rheological method.The results show that the influences of K+ on the stability of silica sol is much larger than that of Na+.Under the low shearing rate,all discussing systems showed the typical disperse system of rheological properties,which is shear thinning.While under the high shearing rate,the resemble Newtonian fluid characteristics has been found. |
